LIFT-PUMP.

SPECIFICATION forming part of Letters Patent No. 233,164, dated October 12, 1880.

Application filed July 9, 1880. (No model.)

To all whom it may concern:

Be it known that I, CHARLES B. PUTNAM, a citizen of the United States, residing at Marion, Iowa, have invented a new and useful Improvement in Lift-Pumps, of which the following is a specification.

This invention relates to pumps for domestic use; and it consists in certain novel features of construction and combinations of parts embodied in an improved lift-pump, which is elegant in appearance, easy of action, durable, and cheap, with the combined advantages of adjustability, removability, ventilation, and protection at once against freezing and drying up, as hereinafter described and claimed.

In the accompanying drawings, which form a part of this specification, Figure 1 is a fulllength front View of my improved pump, drawn to a small scale. Fig. 2 represents a larger vertical section on the 1ine2 2, Fig. 1, and Fig. 3 a vertical section through the base-plate and ventilating-slide in a plane at right angles to that of Fig. 1. Figs. 4 and 5 are plan views of said base-plate and ventilating-slide, showing 2 5 the different positions of the latter. Fig. 6 represents avertical section at and below the frostline in the same plane as Fig. 3, and Fig. 7 is a top view of the elbow shown in section in Fig. 6. Figs. 2 to 7 inclusive, are drawn to one 0 and the same scale, larger than that of Fig. 1.

Like letters of reference indicate corresponding parts in the several figures.

A may represent a cylinder of any approved construction, having an axial discharge-neck,a, 3 5 at top, and furnished with a suitable piston and valves. B B represent two straight sections of pipe, each of which may consist of two or more lengths connected by straight unions, and C an elbow connecting said pipe-sections B B and provided with a stuffing-box, b,in line with its lower neck, 0. D represents a cast-iron airdome, having a neck, d, at bottom, to match the upper neck, 0 of the elbow C, an integral spout, 8, immediately above said neck d, and a 5 central pair of lugs, 6, cast on its top. E represents a cast-iron hand-lever, fulcrumed between said lugs e by a horizontal screw or bolt, f; and F represents a flexible rod, preferably of steel, extending from the working-pivot w of the lever E to the piston within the cylinder A. The rod F has an eye at its upper end, which embraces the pivot screw or bolt to between a pair of cheeks, through which the latter passes. It may be connected with the piston by any approved joint.

G represents a horizontal wooden plank or floor extending across the well or cistern, and provided with a circular hole, It, through which the cylinder A and elbow G will freely pass; and H represents an arched base-plate, of castiron, covering said hole, held in place by screws passing into the wood, and constructed with an integral axial collar, 0 which embraces the pipe-section B and is furnished with one or more radial set-screws, 8 for clamping the latter therein. Said base-plate'is further constructed with a raised guard, g, in the form of an integral vertical tube, which forms a guide for the rod F between the working-pivot w and stuffing-box b.

I represents an annular ventilating-slide fitted to the top of the base-plate H. This slide is held down by the screw or screws 8 while the guard g, in connection with the recessed edge of the slide stops it in its different positions. The "entilating-holes or air-holes 'v are formed in the slide and bed-plate respectively, as clearly shown in Figs. 2 to 5, inclusive.

The parts of the pump are all put together, as shown, with the base-plate H around the pipe-section B The cylinder A is then lowered through the floor G, and the base-plate is attached to the top of the latter, when the pump may be raised or lowered and fastened at the most convenient height by means of the screw or screws the pipe-sections B B having been cut of such length that when adjusted the lower end of the cylinder will be above the bottom of the well or cistern and the elbow 0 immediately below the frost-line. c

The pump may be steadied for use afterit is adjusted by means of oblique braces of the required length extending from the floor to the neck of the dome, as shown in dotted lines at a: 00 Figs. 1 and 2.

When the dome is set low--above a kitchensink, for example-no braces will be required.

By simply drawing from the wood the screws which attach the base-plate (and those which attach the braces, if braces are used) the pump 10o may in a few minutes be removed for inspection or repair with the least possible labor, and as readily replaced.

The elbow 0, supported immediately below the frost-line, provides, by its stufting'box II, for the escape of water from the upper pipesection in winter, to prevent freezing, without emptying the pipe to an unnecessary extent, as illustrated by Fig. (3, and provides for readily stopping the leak when it is not required, the gasket-nut being simply loosened to afi'ord an outlet and tightened to close it. Said elbow also ati'ords an intermediate guide for the rod and renders its operation steady, while in form it is as simple and inexpensive almost as an ordinary curved union, and does not remove the axis of the upper pipe-section from that of the cylinder enough to interfere with the support of the whole by the collar of the base-plat ,asabovedescribed. (Compare Figs. 1, ti. and T.)

The base-plate ll, by its arched form and the provision of the raised guard g, prevents the entrance of dirt and ice or water into the air-holes and around the rod, while it accommodates and cooperates with a ventilatingslide, l,ot' the utmost simplicity, and presents therewith an ornate appearance.

Having thus described my improved lit'tpump,what I claim as new therein,and desire to protect by Letters Patent, is

1. In a lift-pump, the combination of the cylinder A, pipe-sections B ll, elbow U, dome D, lever l), aml rod I united, as herein specified, with the base-plate ll, having an axial collar to embrace the upper pipe-section, a radial screw or screws for clamping said pipesection therein, and airholes around said collar, and the tioor(l,haviug beneath said baseplate a hole, 11, through which the parts beneath can be withdrawn, whereby the pump is rendered adjustable as to height, and also removable at will, in the manner set forth, while provision is made by the same means for ventilating the well or cistern.-

2. In a lift-pump, the combination, with an ordinary cylinder located below the water-line, and having an axial discharge-neck at its up per end, a piston-rod extending upward to the hand-lever, a pipe-section inclosing said rod to a point immediately below the frost-line, and an upper pipe-section extending to the air-drum or escape, the elbow (J, constructed with the necks c 0 and provided with the stufiing-box I), as specified, for guiding and stead ying said rod midway between the lever and piston, afl'ording a leak to prevent freezing up in winter, and providing for readily stopping the leak at will, in the manner set forth.

3. The base-plate H, with its axial collar, radial screw or screws, and air-holes, in combination with the annular ventilating-slide I, for the purposes of a wellor cistern ventilator.

4. In combination with the cylinder A,pipesections 1; l3", elbow (J, dome D, lever E, and rod F, and the floor G, with its hole h, the base-plate II, with its axial collar, radial screw or screws,raised guard, air-holes, and ventilating-slide, as herein specified, for supporting the pump at different heights, providing for its removal at will, and by the same means ventilating the well or cistern, in the manner set forth.
